Lens Metric Scores

Further readings for the Canon EF 16-35mm f/2.8L II USM

To provide photographers with a broader perspective about mobiles, lenses and cameras, here are links to articles, reviews, and analyses of photographic equipment produced by DxOMark, renown websites, magazines or blogs.

With a full-frame 18-Mpix CMOS sensor and twin Digic 5+ processers that’s capable of continuous bursts of up 12 fps – the fastest of any professional DSLR currently - the Canon EOS-1 Dx is the firm’s flagship press camera. We’ve assessed it with over 100 EF mount lenses, to see how well they perform. Read on to find out which models are the best optically and which, if any, you should avoid.

Canon has announced new wide-angle zoom lensesin both their L-series professional line-up and EF-S consumer range. With both lenses boasting new features, and slightly cheaper prices than current options, it’s an exciting announcement for Canon shooters who like to go wide. We preview the specs’ and look at the DxOMark Lens Scores for Canon wide-angle zooms already on the market.

Although overshadowed by its more glamorous sibling, as a moderately priced, highly portable ultra-wide zoom, the EF 17-40mm f/4L USM is a hugely popular model. Read on to find out how well it performs in our labs.

In the lead up to Photokina 2012, Canon announced the new Canon EOS 6D full-frame entry-point model within days of Nikon publicizing their most-affordable full-frame camera to date, the 24-Mpix D600. While the EOS 6D boasted some attention grabbing features including built-in WiFi and GPS and slightly undercut the Nikon on price, it couldn’t match its rival in one or two key areas, namely the less populated AF system and lower resolution sensor.

After comparing the imaging chain of the full-frame Canon EOS 5D Mk III across a raft of lenses, we’ve now turned our attention to the APS-C format EOS 700D / REBEL T5i / Kiss X7i. The 18.1-Mpix ‘Hybrid CMOS’ sensor in this camera is similar to those of the same size and pixel count used in the firm’s other models, including the semi-pro EOS 7D, so it may still be of interest even if you don’t own a EOS 700D / REBEL T5i / Kiss X7i.

The second in our series of selecting the best-quality lenses for your camera concentrates on one of the most highly-anticipated cameras of our time, the successor to the hugely popular EOS 5D Mark II. But by the time it was announced, in early March, it’s probably fair to say Nikon had taken fair amount of interest away by announcing the 36M-Pix D800 and D800E models the month before. Be that as it may, there’s no denying the 22.3 M-Pix EOS 5D Mark III is a remarkably capable camera, and a formidable rival to the Nikon.

DxOMark continues its exploration of the past with this very good wide-angle lens that Sigma first produced for Canon mounts in 2003, and while we’re at it, we’ll use this opportunity to compare it with one of the most best-known lenses on the market, the Canon EF 16-35mm f/2.8L II USM.

Very wide-angle lenses allow photographers to produce an image composed of a large number of objects and to frame very large subjects (such as buildings) at close proximity, and to photograph objects on different geometrical planes that can be very far apart. Such lenses also accentuate perspective, with the most noticeable result being the distortion of straight lines.

Re: Analyze 17.40 Canon lens

Hello!

Thanks for your interest in DxOMark.

We are sorry for the delay on the 17-40mm f/4L, we know some of you are waiting for the results. But as it is an old lens this is not the first priority. We will try to do our best to provide you with the results in beginning of fall because the schedule if full until early September!
